According to a Persian story, Shirin and Farhad were two lovers who died without getting each other. However, Shirin Farhad ki to Nikal Padi has a different meaning, as nikal padna in Hindi is a phrase which means to be very much in luck. Hence, the line here means that Shirin and Farhad are very much in luck.

I love the Hunter song from Gangs of Wasseypur, but it's the lines 'Hai Bahut Bhokali, Na Kabhi Ho Khaali' that hits me the best. But then again, I was wondering how I can translate bhokali in usual words. So decided to explain it a little.

Bhokaali basically is more like a slang, and means something of huge magnitude. Something that can be in a way terrifying, not big, but huge, not necessarily in size.

The lines 'hai bahut bhokali, na kabhi ho khali' means 'it's huge, never gets emptied', other than that 'bahut badi' would do for huge, it's the larger-than-life magnitude of something that is being expressed with the word bhokali.

The word comes from Bhokaal or Bhokal, also the name of a famous comic book character.

Teri Keh ke lunga is a slang which means I'll tell you and take away your dignity. The sentence suggests arrogance and ego, and though it has an underlying sexual overtone in the origin, the usage is not really about anything sexual.

The slang, in original, implies explicitness, but does not have the words exactly. Lena, which literally means to take, is many times used as a slang, for g***d lena, literally to take someone's a**, that is, to f*** someone in the a**.

However, the words teri keh ke lunga literally just mean "I'll tell you and take yours". It doesn't explicitly mention the object. But the complete meaning here would be something like "I'll tell you, and then I'll f*** you in the a**."

Of course, the meaning again here is not literal, and isn't really about anything sexual, but it's just about making someone lose their honor, dignity, and 'keh ke', which means 'after telling', expresses a challenge, that the person addressed won't be able to do anything about it.

For the complete translated lyrics of the Gangs of Wasseypur song with similar title, see THIS POST.

There will moon on one side and bread on the other,
there will be sleep on one side and lullabies on the other,
I'll put the sheet of bread on the moon and sleep
and will tell sleep that I'd come the next day to sing the lullaby..

O, from far away city I found India a place like
all the country must be moving on camels-cows (etc.)
How would I, how would I know,
that there would be skyscrapers in every corner..
India has moved ahead, has won the race of progress..
that's why, that's why..
My imported waist, has searched through the world,
(but) greeting with welcomes, India took my heart..

O god, do a favor (upon me) once,
tell me the philosophy of giving one's heart
this nobody (me) asks for one thing of hers -
O god, tell me where she is. find out,
(because) I am lost without her,
I'm lost, completely lost..
(be-pata literally is one without an address)

While Aamir Khan talked about Female Foeticide on the first episode of Satyamev Jayate, he dedicated a song to the girls at the end of the show. The song, composed by Ram Sampath and written and sung by Swanand Kirkire, is here, with the lyrics and English Translation.

To tell the truth, the words sound more like gibberish than anything else in the song, and I don't really feel they have been added for their meaning. Still, if you insist on knowing, chinta is Hindi for tension, worry, while chita means pyre. And there is also a saying in Hindi that says worry is a way to pyre. चिंता चिता के समान है. (Chinta chita ke samaan hai, literally worry is like a pyre), so if you think the song wants to give you this lesson, you can take it. :)
